3 Claims. (Cl. 222-103) This invention relates to paste tube dispensers, and more particularly to an improved paste tube dispensing holder of the type adapted to automatically dispense a predetermined quantity of paste material therefrom in response to movement of a dispensing lever provided on the holder.

The main object of the invention is to provide a novel and improved paste tube dispensing holder which is simple in construction, which is easy to install, and which is easy to take apart for cleaning and for replacement of the paste tube therein.

A further object of the invention is to provide an improved paste tube dispenser which is inexpensive to fabricate, which is neat in appearance, which is durable in construction, and which is easy to keep in a sanitary condition.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 1 is a perspective view of an assembled paste tube dispensing holder constructed in accordance with the present invention.

Figure 2 is an enlarged vertical cross sectional view taken on the line 22 of Figure 1.

Figure 3 is an enlarged horizontal cross sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a vertical cross sectional view taken on the line 44 of Figure 2.

Figure 5 is a perspective view of the holder of Figures 1 to 4 with the parts thereof in separated position.

Figure 6 is a vertical cross sectional View similar to Figure 4, but showing a modified form of paste tube dispensing holder according to the present invention.

Figure 7 is a fragmentary perspective view showing the cooperating tube-squeezing lever elements employed in the form of the invention of Figure 6.

Referring to the drawings, the holder is designated generally at 11 and comprises a substantially straight main body 12 which is generally rectangular in shape, as shown in Figure 5, and which is formed at its lower end with the thickened portion 13. The upper corner portions of the body 12 are formed with the respective laterally opening L-shaped notches 14, 14. Rigidly secured to the respective corner portions of the straight main body 12 are the respective supporting legs 15, said legs being formed at their ends with the flanges 16 having the downwardly and inwardly inclined side edges 17, respective lugs 18 and 19 being provided at the top and bottom ends of the side edges 17. Designated at 20 and 21 are respective brackets adapted to be fixed to a wall in any suitable manner, said brackets being provided with the respective recessed lugs 22 adjacent their opposite ends to receive the respective flanges 16 of the respective legs 15, said flanges 16 being lockingly engaged in the members 22 to support the main body 12 in a vertical position parallel to the adjacent wall. However, if so desired, the flanges 16 may be disengaged from the receiving elements 22 by exerting upward force on the main body 12, allowing said main body to be removed from the brackets 20 and 21, as when the device is to be cleaned.

The rear surface of the main body 12 is formed with the respective vertical, horizontally serrate-d rib elements 23, 23 arranged on opposite side-s of a vertical rib 24. The top portion of the main body is formed with a horizontal slot 25 which is adapted to pivotally receive the curved arcuate lug 26 provided on the top end of a lever member 27 which is engageable with the vertical rib 24. Designated at 28 is an actuating lever having the depending portion 29 and having the apertured intermediate body portion 30 which is engageable over the thickened element 13 at the lower end of the main body 12. The lever member 28 is formed at its upper end with the spaced parallel fingers 31, 31 which are connected by a pivot pin element 32, said pivot pin element being engageable with a pivot notch 33 formed in the lower end of the lever 27, the lower end portion of said lever being received between the fingers 33, 31. The lower portion of the lever 27 is formed with a guide recess 34 to re ceive a guide lug 35 secured transversely to the pivot pin 32. The ends of the finger elements 31, 31 are adapted to bear against the back surface of the main body 12, so that when the lever member 28 is rotated counterclockwise, as viewed in Figure 4, the pivot pin 32 will be moved rearwardly, causing the lever 27 to be rotated counterclockwise around the pivot notch 33.

Designated at 36 is a housing member shaped to receive a collapsible tube 37, the housing member being provided at its top end with the flanges 38, 38 each of which is L-shaped in cross section and which are adapted to be slidably engaged in the L-shaped notches 14, 14 of the main body 12 and being formed at its bottom end with the parallel fingers 39, 39 spaced apart to receive the thickened bottom element 13 of the main body 12. The long legs of the flanges 38, 38 are arcuate in shape and by virtue of such shape serve to pivotally connect the housing member 36 to the straight main body E2.

The neck portion 40 of the collapsible paste tube 37 is adapted to extend between the fingers 39, 39 as is shown in Figure 4. The inner edge of the notch thus defined in the bottom of the housing member 36 is arcuately cut away, as shown at 41, to provide a relatively close fit with the end portion of the paste tube 37, arranged in an inverted position in the housing member 36.

The housing member 36 includes the respective side walls 43, 43 which are formed with the inclined edges 44, 44, said edges being inclined downwardly and forwardly, as is clearly shown in Figure 5. The side walls 43 are formed adjacent the edges 44 with the ribs 45, said ribs being provided with the arcuately curved widened intermediate portions 46. Designated at 47 is a yoke member having the main body portion 43 adapted to engage against the rear surface of lever 27, said yoke member being formed with the respective yoke arms 49,

49 having the inwardly directed end lugs 50. The arms 49, 49 are engageable around the side edges of the main body 12 and over the ribs 45, the lugs 50 engaging the forward edges of said ribs to support the yoke. main body of the yoke is formed with the upwardly and inwardly extending arcuate fingers 51, 51 whose ends are lockmgly engageable with the serrated ribs 23, 23, the

ends of the fingers 51 and the serrated ribs 23 coasting as pawl and ratchet means arranged to allow the yoke member to gravitate downwardly along the main body 12 but limiting upward movement of the yoke member on said main body, as will be presently described.

The main body 48 is thus formed with a. notch 52, defined between the arcuate fingers 51, 51, which receives the lever 27.

In assembling the device, the housing member 36 is en gaged on the main body 12 by engaging the arcuate shaped The 3 long-legs of 'the flanges 38, 38 through the L-shaped notches 14, 14. The arcuate flange 26 of the lever member 27 is then engaged through the slot and the arcuate pivot notch 34 of the lower end of lever 27 is then engaged on the pivot pin 32, the member 28 being then arranged so that its apertured intermediate body portion 30 is en-' gaged over the thickened lower portion 13 of the main body 12. The yoke member 47 is then engaged over the main body 12' with the arms 49, 49 of said yoke member extending'past the top portions of the ribs 45, the lugs 50 engaging theforward surfaces of said ribs. in this position, the main portion of the yoke member bears against the rear surface of lever 27 withthe ends of the fingersSl, 51 engaging the serrationson theribs 23, 23.

When the parts are arranged as above described, the flanges 16 on the ends of the legs 15 may then be engaged in the receiving elements 22 on the brackets 20 and21, whereby the device is ready for use. The paste tube. 37' may then be placed in inverted position in the housing member 36, with the neck'of the tube projecting between the fingers 3?, 39, as above described. When it is desired to dispense paste material, the user rotates the depending lever element 29 rearwardly, namely, counterclockwise around the pin element 32, as. by pushing against the element 29 with his totoh brush. This causes the paste material to be extruded from the neck of the tube onto the tooth brush placed subjacentthereto.

When removing an evacuated paste tube to replace same with anew tube, the yoke member 47 is raised to its. upermost position wherein arms 4? engage the lower. edges of upper legs 15. The lower end of housing member 36 is swung outwardly away from main body 12. until the arcuate shaped long legs of the flanges 38, 38 substantially engage the top edges of upper legs 15. The the housing member 36 is moved away from main. body 12,until' lugs 50 are engaged by the forward edges, of. the ribs 45. The evacuated tube may be then removed and. replaced by a new tube.

It will be understood that the main body 1-2v is sufiiciently narrow in width to be received withinthe housing; member 36, namely, between the side walls 43,43 of. said housing member and that. the arcuate shaped long legsof the flanges 33, 33 are rotatable as well as slidable in the L-shaped grooves 14, 14. The main body member12.

is formed with the vertical rib 24 between theverticai serrated ribs 23, 23, saidvertical rib 24 being receivable in a vertical grove 55 formed in the lever 27.. When the level-member 28 is rotated counterclockwise around the pivot element 32, the lever 27 is rotatedcounterclockwise around its pivot point, namely, around the slot 25, as

viewed in Figure 4, acting against the yokemember 48;

and causing the yoke member to transmit aforce. onjthe housing 36- tending to rotate said housing counterclock wise, asviewed' in Figure 4. The-housing member 36 is thus rotated toward the main body 12,. applying squeezing force to the paste tube 37, and causing the contents of the tube to be extruded fromits. neck 40. When asuflicient' quantity of paste material has been discharged from the tube to cause the tube to fit. loosely in the housing member 36, the yoke member 47 gravitates downwardly,

first-tends to rotate in a clockwise direction, until, the,

upper extremity thereof engages the upper. portion of main body-'12. The housing member thereafter tends; to rotatein a counterclockwise direction, as. aboveidescribed.

The rib 24 on the back of the main body 12 is of. substantiakl eight, and cooperates withthe grooves55. in the lever 27to maintain the lever in. proper working. position,

Therefore, when force is transmited from: yoke;

at all times. The main body portion 48 of the yoke member acts against therear surface of thelever 27 tourge the lever toward the main body 12 and to maintain the pivot notch 33 at the lower end of the lever in engagement with the pivot pin 32.

In the modified form of the invention shown in Figures 6 and 7, the main body member of the device, shown at 12, is formed in its lower portion with a slot in which a transversepivot pin 61 is secured. The hollow lever member; shown at 27', has a forward transverse wall portion 62-andis formed. in its: rear, wall opposite wall portion 62 with a longitudinal slot 63. An auxiliary lever bar 64 is provided, said lever bar 64 being formed at its lower end withan arcuate bearing lug 65 received in slot 60 and pivotally engaging around pin 61, as shown. Auxiliary lever bar 64 extends upwardly through the hollow lever member 27' and is engaged through the slot 63. A pivot shoulder 67 is provided on the forward edge of lever bar 64 which is pivotally engageable'with the lower edge of transverse wall portion 62. The upper rear edge portion of lever bar'64 is engageable with the main body portion 48 of yoke member 47, as shown in Figure 6.

Normally, the auxiliary lever bar 64 is substantially fully housed in the hollow lever member 27'. When the depending lever element 28 is swung rearwardly around the pivot member 32, the hollow" lever 27 is rotated counterclockwise aroundits pivot connection 25, 26, applying a force to auxiliary lever 64 at shoulder 67 which rotates lever 64 clockwise, as viewed. in Figure 6; around its pivotal connection 65, 61. The upper end of lever 64 thus acts against the main body 48 of yoke member 47 torotate said yoke member rearwardly and" to cause. squeezing force to be applied to the paste. tube. This action occurs when the tube is fullfor has a substantial,

the paste material has been substantially discharged from the upper portion of thetube by the. actionoftheauxiliany lever member 64 above described, the remainder of! the paste material is discharged by themore. direct action of the lever 27', so that complete utilizationof. the;con.tentsj of the paste tube is assured.

It will'be noted that the housing member 36 is arranged to receive a paste tube nearly as, long as, they housing member itself, and fulland round almost. to. the end: of

the tube, the device being arranged sothat the surfaces which apply squeezing pressure on the tube arewnearly parallel. This is accomplished by the provision of the. arcuate shaped legs of the flanges, 38,38 at. the top end. of the housing member which are slidably engaged in the L-shaped notches 14, 14 in the upper. portion of the. main body 12;.

Whilecertain specific. embodiments of. an, improved paste tube dispensing holder has been disclosedin. the; foregoing description, it will. be understood that. various modifications withinthe spirit of'the invention may occur. to'those'skilled' in the art. Therefor it is. intended; that no limitations beplaced on. the-invention. except as, defined" by the scope of the. appended claims.
